What is voltage line?

The line voltage is defined as the potential difference between two phases in a three-phase system or polyphase system. It is denoted by VL volts. The Phase voltage is the potential difference between one phase to the neutral point in any three-phase system or poly-phase systems and it is denoted by Vph. in volts.

What is the symbol for V and DC?

“V” with a wavy line over it = AC voltage. “V” with one dotted and one solid over it = DC voltage. “mV” with one wavy line or a pair of lines, one dotted and one solid, over it = AC or DC millivolts.

What is a 240V line?

A 240-volt outlet is a power line with two 120 volt lines (Phase A & Phase B) with an acceptable range of voltage from 228 volts to 252. Historically, 240 has been referred to as 220, because the voltage range starts in the two-twenties. Both phases (A & B) are fed into the house from the streetside power source.
